Hey I just understand nothing... You put holes in a mask and with magic you get... what, brither images ? sharper images ? better looking images ? and how do those holes help, can anyone explain the magic ?


yes, i can explain. If you read again you will see that the process is used when someone is viewing a bright space object, IE.. a very bright star, the moon, the planets... In the path of light (see the image?) an mask is placed with holes in it. Think of a paper plate with large holes. These holes are placed before the viewers eyepeice in the path of light to limit some of the incoming light from obects that are not wanted to be seen. This increase resolution and creates a MUCH sharper image because it reduces the runnoff of light from the other objects that are in the field of view. You can test this at home with a True apature mask. Take a small tellscope and look at the moon with a 20mm eyepeice. you will see that details of the moon are hard to see (if it is a closer to full moon and your telescope is not complete junk :P.) now create a cardboard cutout that creates an oval or circle shape about half as wide as the opening of your telescope and tape to the front. You should see very large improvements on what you can see for detail on the moon. FYI this used to be employed on a large scale basis prior to the release of Filters which now can give you exactly how much incoming light you would like. Hope any of that helps.


Why mention the file format of one of the references? '...as a PostScript file which can be viewed in GSView'. This does not seem to add useful information at all, one could as well mention that the other references are in HTML format and can be viewed with Internet Explorer.
